MADlSON D. SHIPMAN, OF DE KALB, ILLINOIS.

SEPARABL BUTTON.

SPECIFICATION forming pari; of Letters Patent No. 391,200, dated October 16, 1888.

Application filed April 520, 1887.

To all whom, it may concern:

Beit known that I, MADIsoN D. SHIPMAN, a citizen of the United States, residing at De Kalb, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Separable Buttons, of which the following is a specification.

My invention relates to separable buttons for gloves, Ste., in which the button-head has two clamping-shells for receiving and clamping the material, and contains an elastic studholding opening and a stud constructed to assume, when the stud is being fixed to the material, a suitable bulb-like form' for holding with the said button-head; and the invention consists of the arrangement and construction and combination of parts hereinafter particularly described, and set forth in the claims.

The accompanying drawings, forming a part of this specification, represent my improvements on an enlarged scale, and the same letters of reference marked thereon indicate si1nilar parts throughout the several views.

In the drawings, Figure 1 is a sectional elevation of both the buttonhead and stud, showing their manner of construction and connec tion of parts and connection with the fabric. Fig. 2 is View of an elastic walled tube for holding with the stud and its connected shell. Fig. 3 is a sectional view of thc outer shell of the button-head and the elastic walled tube and inner shell of the buttonhead attached to the fabric. Fig. 4 is a sectional elevation of the stud and its means of attachment to the fabric. Figs. 5, 6, 7, 8, 9, 1.0, 11, and 12 are detail views of parts of button in Fig. 1. Fig. 13 is a sectional view of a modified form of shell and tube combined. Figs. 14 and 15 are detail views of a modification of a shell for attachment with the outer shell and its connected tube. Fig. 16 is another modification of the outer shell and stud-receiving tube connected therewith. Fig. 17 is a modification of the under shell and its closing-disk.

The same letters refer to like parts throughout the drawings.

In the drawings, A, Figs. 1, 4, and 10, represents the stud when in form for use and secured to the fabric. This stud is at first made with a slightly-tapering and hollow form, as shown in Fig. 9, and preferably integral with base-flange a, and is subsequently made with a bulbous or swelling form of upper portion, as will be fully described. This stud is cmployed with coacting washer B for securing it with the material. This washer B is made with a central perforation, b, of diameter corresponding with that of the lower end portion of the stud neighboring its base-flange a. lf preferred, this washer can be provided with an up Wardly-projected ring-Bange, b', as shown in Figs. 1, 4E, 7, and 8. After stud A (in its tapering form shown in Fig. 9) has been passed through the material from one side thereofand through the central perforation in washer B, when the latter is applied to the opposite side of the material, the operator will with a suitable instrument (applied with force to the opposite ends of the stud) upset and swell the upper portion of the stud, so as to give it the bulbous form, substantially as illustrated in Figs. 1, 4, and 10, which will be suitable for holding with the catching device in the coacting button-head, secured also to the matcrial.

C is an elastic stud-holding tube for holding the button-head united with the stud A. This stud-holding tube has its upper end made with or connected with the shell D, and can project centrally from its upper end downwardly through the concavity of shell D to a short distance past a line on a plane with the lower or base end of said shell, as shown, and its lower end is free from connection with any other piece or part in the button-head, and is preferably provided with the annular internal ridge or projection, c, which operates to effect a contraction of the diameter of the bore of the lower portion of this stud-holding tube, as shown. The side wall of said tube Gis provided with one or more slits, c', which are eX- tended from its lower and free end edge to near its line of connection of the tube with shell D, so as to permit the wall portions between the said slits or neighboring the same to be outwardly extended to such an extent as to allow the internal ridge or projection, c, to pass over the swell of the stud A, so that said swell will be fully received within the larger portion of thebore of tube C above said ridge, as shown in Fig. 1. This tube C is shown in Figs. 1, 3, 5, 13, and 1G to be made Solid with shell D, while it is shown to be secured with said shell by its flange holding with thelatter.

IOL)

Shell D is preferably made with a concaveconvex form, and, as applied to the upper side of the material, L, the button-head of which it forms a part is to be secured.

5 E is another shell-shaped piece made with said shell, as shown in Figs. 1, 3, 6, and 14, or

by a disk, E', having its circumferential edge clluehed on thelower edge portion of said shell, as shown in Fig. 17. One or more annular n arrow corrugations, fv, are made with the outer side of thewall of tube C at near its line of union with shell D. Made central in shell E is perforation e', having a diameter correspond- :lng withthe upper end portion of tube C and so asto tightly t with the same, with the edge of sa1d perforation engaging with some one of the annular corrugations fu. In the closing piece E 1s made the central perforation, et, of diameter sufficiently largeto allow the bulbous head of stud A to pass through to and into the studholding tube C.

In securing this improved button-head to the fabric or leather, L, the upper side shell, D, is applied to the upper side of the material, with the stud-holding tube C passed down through the fabric orleather, when under portion or part of the button-head will be applied to the under side of the fabric, with tube C entering the central perforation of shell E, when by a suitable instrument the upper shell,

' D, and lower shell, E, will be forced toward each other, with the former clamping on the upper side of the material and the latter on the under side of same, whenthe corrugations u on tube O will hold with the'metal edge of the central perforation in shell E.

If the metal of shell E be stiff, I prefer to make in it two or more slits, s, from its central perforation outwardly to a short distance, as shown in Figs. 14 and 15, so that the metal neighboring the said central perforation will yield slightly and be made to more readily spring into place in one of the annular corru- 4gations o, made with the stud-holding tube C.

By means of the perforation e2 in the shellclosing piece E the head of the stud will be permitted to readily pass into the slitted tube O, to engage with the elastic end of the tube, while at the same time the edge margin of perforation e2 in the shell-closing piece will hold with the lower portion of the stud below the head of the same, so that the draft on the the perforation e, and thereby relieve the seci tional wall of the tube from excessive strain.

stud will be received on a side of the edge of What I claim, and desire to4 secure by Letters Patent, is-

1. In a separable button, the combination..

with the bulbAshaped stud A, of a button'head provided with the tube C, having in its side walls one or more slits, c', and having its free end portion provided with the annular inten nal ridge or projection, c, at a short distance above its free end edge, so that the walls of said tube will be adapted to be expanded when the head of the stud is passing said annular internal ridge, and the ridge be made to eugage with the neck of the stud at about ou a line with the material the button-head is secured to, substantially as and for the purposes set forth.

2. In a separable button, the combination, with a slitted elastic walled tube having a solid connection with the upper shell of the buttonhead, and the corrugations o at near the line of union of said tube with -said shell, of the lower side shell provided with a central perforation and adapted to engage and hold with the corrugations in the said tube, so that the said upper and lower shells will be made to clamp the material between, while the said tube is made to hold with the engaging-stud, substantially as and for the purposes set forth.

3. In a separable button, the combination, with the concavo-convex shell D, connected with a stud-holding tube, which is provided at near its line of connection with said shell with the corrugations u, of a coacting inner concavo-convex shell, having a central opening with an edge which is calculated to engage with said corrugations when this under shell is forcibly pressed toward the upper shell, substantially as and for the operations and purposes set forth.

4. In a separable button, aud in combination with a stud-holding tube having its side walls slitted through its free end edge toward its secured end, a buttonheadelosing piece, E', which has a central perforation, e2, which will admit the passage of the head of thel stud and also hold with its lower portion, substantially as and for the purposes set forth.

5. In a separable button, the hollow or shellform stud A, having with it the disk-form base a and the holding-head, incombiuation with the washer B, having its central perforation b, containing the contracted neck below the bulb-form head produced from the tapering shell, as described, and clamping the fabric, substantially as and for the purpose set forth.
